Back then, the incubator was hosted on-premises at Red Gate Software; they're the friendliest bunch of folks I've ever met, and always went out of their way to help us however they could. About once a week, we'd have a one-hour lecture by one of the Red-Gaters giving us a "crash course" in some area of the software business -- sales, marketing, customer service, product management, and more.
We also had the chance to have beer and pizza with some of the big names in the startup world: Peldi (of Balsamiq), Ryan Carson (of Carsonified), and even Joel Spolsky. It's great to have a few minutes to bounce ideas off people who have built a successful business in the same way you want to, and it was really cool of them to take the time to give us advice.
I could go on for ages, but instead I'll wrap up with this: it'll tough -- because Springboard offers you a lot of learning opportunities (in addition to the work you'll need to do to build your startup) -- but going through the program will be the best thing that ever happened to you (and to your startup).
